Studying Cycles: Chemistry and Climate
|
| Topic: Climate |
01/24/11 |
| New studies have shown that scientists have underestimated the effect that two chemical compounds may have on Earth's climate. Carbon dioxide and nitrous oxide can contribute to global warming and climate change, and might bring about a climate on Earth that life has never experienced before. |

Time for Climate Change
|
| Topic: Climate |

| Earth's climate could take 100,000 years or longer to recover from rising CO2 if we don't mitigate our carbon emissions. Scientists studying one ancient bout of global warming 56 million years ago found that CO2 took about 30,000 to 40,000 years to settle out of the atmosphere. |

| Topic: Climate |
11/14/10 |
| A new study shows that variations in carbon dioxide 40 million years ago were tightly coupled to changes in global temperature. Understanding the relationship between the Earth's climate and carbon dioxide can provide insight into the extent of future global warming caused by the activities of humans. |

Species in the Fast Lane: Speeding Up Growth and Metabolism
|
| Topic: Climate |
11/01/10 |
| New research indicates that global warming could be having devastating effects, even with small shifts in tempertaure. Even some of Earth's most reilient species may find the changes too difficult to survive. Studying the effects of climate change can help us understand life's future on Earth. |

| Os oceanos são críticos para a sobrevivência da vida na Terra, mas a mudança climática pode estar causando danos irreversíveis a estes frágeis sistemas. Qual papel a acidificação, o derretimento de gelo e o aumento da temperatura de superfície desempenharão na habitabilidade futura de nosso planeta? |

Hunting for New Habitats
|
| Topic: Climate |

Climate Change before it Goes Global
|
| Topic: Climate |
09/27/10 |
| Whiffs of oxygen may have been present on Earth before the Great Oxidation Event. This may have allowed for niche environments for oxygen-dependent organisms before the global atmosphere became oxygen rich. This isn't the only example of how climate change can first occur regionally rather than globally. |

Plants and the Carbon Capture Question
|
| Topic: Climate |
09/13/10 |
| We have a long way to go in understanding climate change, but we do know that complex interactions between plants and the climate of Earth go well beyond the Carbon Cycle. Studying the links between life and climate will aid in understanding life's future on Earth. |
